Census Fact Sheets are designed to assist in the use and interpretation of Census data. They provide a summary of conceptual and data issues, and changes that have occurred since the last Census. Fact Sheets are developed and produced for a variety of areas, with a focus on a particular question of the Census form. The need for the development of a Fact Sheet is determined by the number of issues raised in a particular area. If there are numerous enquiries, a Fact Sheet will be developed to provide an explanation of the issue.
